COIN-OPERATED HAN D-POWER-TESTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,933, dated April 9, 1889.

Application led September 19, 1888. Serial No. 285,805. (No model.)

To cI/ZZ whom, t 11mg/ concern:

Be it known that we, ALBERT O. MEADY and CHARLES B. BoswoErH, citizens of the United States, the former residing at Somerville and the latter at Everett, both in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Coin-Operating Hand-Power- Testing Machines; and we do declare the fol- 1o lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon,

which form a part of this specification.

Figure l is a sectional rear elevation, Fig; 2 aA vertical median and transverse section, and Fig. 3 a horizontal and median section, of

zo a coin-operating hand-.power-testing machine provided with our invention. Fig. Ll is a side view of a portion of the piston-rod, and Fig.

5 is an inner side View of the dog.

The nature of our invention is deiined i1 2 5 the claims hereinafter presented.

In the drawings the casing of the machine is shown at a, it being supported on a standard, b, within which is a receptacle (not shown in the drawings) to receive the coin after 3o passing from t-he chute, into which it falls on its release from the dog. A handle, A, is fixed to the case, within which is arranged a movable handle, B, adapted to slide in the case and adjust-ably connected to a piston-rod, O, the

3 5 said rod 'having a'male screw, l, which screws into a female screw, 2, formed in the shank of the movable handle, a nut, 8, being applied to the male screw to be turned against the end of the shank of the handle B to securely 4o hold the rod in position when properly adj usted. The shank of the handle B may be prismatic or angular, and, owing to its adjustable connection to the rod C, the handle B can be made to stand at a proper distance 4 5 from the handle Ato be conveniently gripped by the hand.

Within the case a, and for supporting the operative mechanism therein, is arranged a frame, c, as shown, the chute M, into which the coin drops after unlocking the dog, here- 5o inafter described, from the piston or slide rod, forming a part of said frame.` D is a cylinder fastened to the frame, and in which the piston-head D', attached to the rod O, slides when operated by the handle B. A spring, E, encompassing the piston-rod, bears against and between the piston-head D and the cylinder-headtl, as represented, and projecting from the said head d are ears e f, to which is pivoted so as to swing in a horizontal 6o plane the dog J, the pivot being shown at g. The cylinder D may be dispensed with, and the head d, for supporting the rod and furnishing a bearing for the spring, fixed to the frame instead of to the cylinder, the object in using the cylinder being to provide an airc ishion for the piston, to prevent its too sudden bringing up against the end of the cylinder on the release of the handle B from the hand of a person. 7o

The dog J is provided near its pivoted end with a vertical groove, h, which extends through it from top to bottom, and is open on the side of it next the piston-rod. Extending from the rear side of the dog and into the groove h is an adj Listing-screw, t', (see Figs. 2, 3, and 5,) which admits of the use of coins of different sizes or values to operate the machine, if desired. The free end of the dog is provided with a tooth, 7c, which enters a notch, 8o Z, in the piston-rod, and near the pivoted end of the dog a spring, m, is fastened to it, the free end of which bears against the cylinder, whereby the tooth of the dog is kept in engagement with the notch l in the rod.

The circumference of the piston-rod O in that portion of it near the groove h in the dog and on opposite sides of said groove in the direction of the axis of the said pistonrod is reduced, as shown at n n', (see Figs. 3 9o and 4,) a portion of said circumference remaining between the two reductions, so as to form a rib or abutment, o, which is arranged to stand on one side of the said groove-viz., that side nearest the pivot of-the dog-so that when a coin, R, is deposited in said groove h it will stand between the abutment o and the handle B, the side of the coin nearestV the pivot g touching or nearly touching the abutment o and the edge of it bearing against the face of the reduction n of the rod C, and also against the end of the adj listing-screw il. (See Fig. 3.)

Pivoted to the piston-rod C at p, and connected to a sector, G, at q, is a link, F, slotted, as shown at o', to admit of movement of the link on the pin q. The sector G, pivoted to the frame at s, connects with a pinion, Il, secured to a short shaft, t, supported in abearing, u, in the frame, and extending' through the same and the dial n. Said shaft has an indexhand, w, provided with a pin, 4, fastened near to its upper end, as represented.

A'n auxiliary hand, Qc, pivoted on a stud arranged in the glass plate y, as represented, is borne against by a friction-spring, z, supported on said stud between the glass plate and the hand, with sufficient force to hold the said hand at any point on the dial to which it may be moved by the pin 4 of the hand 1U, which pin bears against one edge of the aux iliary hand.

.A st-ud, l, projecting from the frame, serves as a stop for the sector, and when said sector is against it, as shown in Fig. l, the ind exhand stands vertically or points tothe zero-mark on the dial. Acoin-guiding tube, L, extends from an opening in the top of the case nearly to the top of the dog J, and directly over the groove h therein, and said tube is secured at its lower end to the ear e.

The operation of the hereinbefere-described machine may be thus described: By inspection of Figs. 2 and 3 it will be perceived that on dropping'a coin, R, into the tube L it will bring up against the end of the screw t' and the face of the reduction n in the piston-rod, and the side of the coin next the pivot g of the dog will touch or nearly touch the abutment o. On moving' the piston-rod by means of the handle B, the abutment 0, bearing against the coin, will thereby swing the dog on its pivot, and as soon as the point of the tooth 7o clears the notch Z in the rod C' the outer end of the slot a in the link F, pivoted to the rod, as shown, will bear against the stud q of the sector, and, the rod C continuing to move, the sector G will be turned on its pivot, and thus the pinion lvl' on its bearing and the hand w moved around on the dial, and its pin 4, bearing against the registering-hand will carry said hand to the point on the dial indicat-ive of the pressure applied to thehan dle and rod, at which point it will remain after the return of the rod C and the hand w to their original positions until moved back by applying the thumb and forefingers to and turning the button Z9', secured to the stud supporting the hand ft, and arranged on the outside of the glass plate, as shown.

It will be observed that the coin R is caused by the abutment o to operate the dog, and as soon as the said dog is turned back far enough to let the said abutment pass by the edge of the coin the said coin will be released, and

will drop out of the groove Z1, and into the chute M, and through the saine into the receptacle made in the standard Z) to receive it, and at the instant the coin is released from the abutment the tooth 7c of the dog will be forced by its spring n1, against the rod C and be in readiness to lockinto the notch Z inA the rod C on its return to the starting-point.

The casing a is provided in its back with a door, O, hinged at c', and having a lock, P, by which it is secured to the case when closed.
